I am working on a single page application using the asp.net mvc 5 template and registering external logins (google in this instance) fails with a validation exception - "The UserId field is required." the code in question:
// POST api/Account/RegisterExternal [OverrideAuthentication]
[HostAuthentication(DefaultAuthenticationTypes.ExternalBearer)]
[Route("RegisterExternal")]
public async Task<IHttpActionResult> RegisterExternal(RegisterExternalBindingModel model)
{
try
{
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
ExternalLoginData externalLogin = ExternalLoginData.FromIdentity(User.Identity as ClaimsIdentity);
if (externalLogin == null)
{
return InternalServerError();
}
IdentityUser user = new IdentityUser//(model.UserName);
{
UserName = model.UserName
};
user.Logins.Add(new IdentityUserLogin
{
LoginProvider = externalLogin.LoginProvider,
ProviderKey = externalLogin.ProviderKey
});
IdentityResult result = await UserManager.CreateAsync(user);
IHttpActionResult errorResult = GetErrorResult(result);
if (errorResult != null)
{
return errorResult;
}
return Ok();
}
catch (Exception exception)
{
throw;
}
}
I appreciate the help
The fix was simple but I find it strange it that the code generated by the template doesn't work out of the box. The IdentityUserLogin object has a UserID property that must be set.
IdentityUser user = new IdentityUser
{
UserName = model.UserName
};
user.Logins.Add(new IdentityUserLogin()
{
LoginProvider = externalLogin.LoginProvider,
ProviderKey = externalLogin.ProviderKey,
UserId = user.Id
});
IdentityResult result = await UserManager.CreateAsync(user);
